Below grade 10 the guide publishes one estimate across all graders, so these rows are not PSA, BGS, CGC or SGC prices, and a low slabbed grade can sit below a clean raw copy. Grade 10 is estimated per grader.
Each point is the last stored observation that day for this printing, condition, grader, autograph status and source. Gaps mean no observation; guide estimates and asking prices are not completed sales.

SuperCatch Expert Analysis
Market Value Insight
This 1987 Topps Mark Davis card represents a mass-produced entry-level piece from a high-print run era, placing it at the lowest tier of market value. While the player's tenure with the San Francisco Giants provides basic historical context, the lack of special attributes or grading premiums keeps its value nominal. It serves primarily as a budget-friendly acquisition for those completing base set requirements rather than as a significant financial asset.
Rarity Breakdown
The card possesses no scarcity-enhancing features such as serial numbering, short prints, or parallel variants, indicating it is a standard base card from the 1987 Topps set. This unrestricted production method means supply is abundant and effectively unlimited compared to limited-edition counterparts. Consequently, the item relies entirely on its status as a common issue within the broader product line.
Investment Outlook
As a non-rookie, non-special parallel card from a vintage mass-market set, this item lacks the specific demand drivers that typically fuel appreciation in the sports card market. Collector interest is likely limited to those seeking specific team or player completions for their base collections. Long-term growth potential is minimal given the high availability and lack of unique selling points beyond its vintage age.
